PRIORITY CLAIM

This application is the National Stage of International Application No.PCT/US2008/065364, filed on May 30, 2008, entitled UNIVERSAL CATHETERSECUREMENT DEVICE, which claims the benefit of U.S. Provisional PatentApplication No. 60/941,647, filed June 1, 2007, both of which are herebyexpressly incorporated by reference in their entireties.

BACKGROUND

It is often necessary to introduce fluids and liquid medicationsdirectly into a blood vessel of a patient. Various types of cathetersare often used in combination with connectors and syringes. A catheteris essentially a tube inserted through an incision in the skin into ablood vessel in the patient's body, generally without surgery. A simpleintravenous (IV) line is usually acceptable for introduction of fluidsand liquid medications into a blood vessel for short term general use.IV lines are typically inserted into a patient's arm by inserting acatheter that contains a needle which pierces the skin. The needle isthen removed and discarded while the soft catheter stays in the bloodvessel. The external portion of the catheter is usually taped in placeor secured with a self-adhesive dressing to the patient's arm. Thisexternal portion often consists of flexible tubing and a locking hub.For longer term and more specialized needs, different types of cathetersor other devices are used. Peripherally inserted central catheters(PICCs) are frequently used to provide medications or fluids to homecare patients over longer periods of time. PICCs may also be used forfrequent blood sampling.

IV lines commonly remain in patients for days at a time, while a PICCline and similar catheters may remain in place in a patient for severalweeks or months. In both cases it is important that movement of thecatheter be minimized. If the catheter is not secured in place, it maybe inadvertently displaced from the intended location. Consequently,medication delivered through an IV or PICC line may then be released atan incorrect position within the blood vessel. Repeated back and forthcatheter movement, or pistoning, can cause irritation of the bloodvessel, disrupt proper introduction of medications to the patient, andincrease the potential for bleeding or infection at the catheterincision site. If extensive movement occurs, the IV or PICC line couldeven come out of the patient, interrupting delivery of medication andrequiring re-insertion, often with hospitalization.

In the past, catheters were simply taped into place on the patient'sskin. However, taping is time consuming and labor intensive. Tape alsocollects bacteria and must be frequently removed and replaced. Moreimportantly, taping is not necessarily effective in securing a catheterin place. Sutures have also been used to attach a catheter to a patient.With sutures, the catheter is stitched onto the skin. Sutures, however,can also be a source of infection, can cause pain and inflammation, andcan make it more difficult to clean around the incision site. Suturesalso require time and skill to place, and can cause scarring.

More recently, manufactured catheter anchors or securing devices havebecome widely used. These devices are designed to secure specificcatheters in place. While various designs have been used, these devicesgenerally have an adhesive-backed pad that bonds to the skin over alarge area. The catheter is secured into or onto a catheter anchordesigned for holding the catheter. However, engineering designchallenges remain in providing reliable, secure and efficient anchoringdevices. Further, because existing anchoring devices are generallydesigned for a specific type of catheter, multiple anchors may be neededto accommodate use of different types of catheters in hospitals,clinical settings, or other arenas. This adds to the cost and complexityof sourcing, inventory, storage, and selection of the anchoring devices.Accordingly, improved anchoring devices are needed.

SUMMARY

DETAILED DESCRIPTION OF THE DRAWINGS

Various embodiments of the invention will now be described. Thefollowing description provides specific details for a thoroughunderstanding and enabling description of these embodiments. One skilledin the art will understand, however, that the invention may be practicedwithout many of these details. Additionally, some well-known structuresor functions may not be shown or described in detail so as to avoidunnecessarily obscuring the relevant description of the variousembodiments.

The terminology used in the description presented below is intended tobe interpreted in its broadest reasonable manner, even though it isbeing used in conjunction with a detailed description of certainspecific embodiments of the invention. Certain terms may even beemphasized below; however, any terminology intended to be interpreted inany restricted manner will be overtly and specifically defined as suchin this detailed description section.

Where the context permits, singular or plural terms may also include theplural or singular term, respectively. Moreover, unless the word “or” isexpressly limited to mean only a single item exclusive from the otheritems in a list of two or more items, then the use of “or” in such alist is to be interpreted as including (a) any single item in the list,(b) all of the items in the list, or (c) any combination of items in thelist.

A universal securing device for holding catheters or catheter fittingsof various designs, shapes, or sizes may include a base and a cover. Thecover may be connected to the base by a hinge which allows the cover tobe lifted open or pushed down into a closed position, to secure acatheter fitting or similar device. The base and/or cover have locatingelements configured and arranged to fit around catheters and catheterfittings of various shapes and sizes. The catheter fitting is placedinto or onto the base from above. The locating elements preventsubstantial movement of a catheter and/or catheter fitting in multipledimensions.

A catheter fitting to be held by and of the devices described hereinincludes any type of catheter fitting, attachment, accessory, connector,etc., whether integral with the catheter or as a separate piece from thecatheter. A catheter may also refer to a catheter alone or incombination with any type of catheter fitting.

Latching elements, which may be located on squeezing arms, hold thecover onto the base. Capture elements may be located on the under sideof the cover to compress a catheter fitting, securely holding it inplace against the base, in the closed position. The catheter may be heldsecurely in place on a patient once the securing device is attached tothe patient. The catheter can be removed from the base by disengagingthe latching elements, for example, here by squeezing the squeezing armstoward each other. Thus, a catheter and catheter fitting of variousshapes and sizes can be securely held by a single securing device andcan be quickly and easily attached to or removed from the patient.

The devices described herein may be used with, e.g., PICC lines, IVcatheters, Foley catheters, heart catheters, J-loops, epidural lines orcatheters, arterial lines or catheters, and various others. In additionto a catheter, the securing devices herein may be used to secure othertubes, cables, wires, and various other medical devices as well.

Turning now to the drawings, as shown in FIGS. 1-9, a securing device 20has a base 26. As shown in FIG. 2, the base 26 may be contoured and mayhave one or more locating elements 40 which are shaped and dimensionedto be positioned around and hold catheters and catheter fittings ofvarious shapes and sizes, such as catheter fitting 32 and catheter 30.In FIGS. 2-5 and 8-9, the locating elements 40 include rectangularshaped walls, however, locating elements may be round, square,hexagonal, etc. and they may take on various forms in addition to wallssuch as pegs, columns, etc. The base may vary in size and typically isabout 2-3 inches long and about 1-2 inches wide.

Referring to FIGS. 3-4, the locating elements 40 extend up from the base26. In this particular embodiment, the locating elements include atleast one front wall 41 and a pair of back walls 46. The front and backwalls are spaced apart in a front to back direction as indicated byarrow 49, which runs along a longitudinal axis identified by theimaginary line marked Y shown in FIG. 3. A front wall 41 shown in FIGS.3-4 is made up of at least one curved end wall 42, at least one angledfront wall 43, at least one elbow 44. A semicircular trough 45 may bepositioned slightly forward of the angled front wall 43 as indicated byarrow 49 and may be connected to the elbow 44. A raised post may extendup from at least one elbow 44. The back walls 46 are preferably angledand are each connected to a post 47. The first and second posts 47connected to either back wall 46, can be the same size or they maydiffer in size. In general, the locating elements 40 may besubstantially symmetrical side-to-side about the longitudinal axis orcenterline Y. The locating elements 40 are arranged and positioned toallow PICCs and other catheters of various shapes and sizes to be placedonto the base 26 and held within the securing device 20. The locatingelements 40 are arranged in a manner to help position catheters andcatheter fittings of various shapes and sizes and prevent substantialmovement of a catheter and catheter fitting in various dimensionsrelative to the base, e.g., side-to-side and back-to-front, axialmovement, as well as rotational movement.

Referring to FIGS. 3-4, in one embodiment the locating elements 40 arearranged such that a front wall 41 is separated from the back wall 46 bya dimension AA which extends straight back, parallel to the longitudinalY axis, from the rear most tip of curved end wall 42 of front wall 41 tothe back wall 46. The front wall 41 may also be separated from the backwall 46 by a dimension BB which extends from the rear most tip of curvedend wall 42 of front wall 41, straight back and perpendicular to theback wall 46. Also, the inner edge of the first or left post 47 may beseparated from the inner edge of the second or right post 47 by adimension CC running generally parallel to a lateral axis X. Also, thefirst or left elbow 44 may be separated from the second or right elbow44 by a dimension DD running parallel to dimension CC.

In one embodiment, dimension AA may be less than dimension BB. Also,dimension CC may be greater than dimension DD. In another embodimentdimension AA may measure about 0.34 to 0.38 inches, preferably 0.35 to0.37 inches, or more preferably 0.36 inches in length. Dimension BB maymeasure about 0.37 to 0.41 inches, preferably 0.38 to 0.40 inches, ormore preferably 0.39 inches in length. Also, dimension CC may measureabout 0.35 to 0.39 inches, preferably 0.36 to 0.38 inches, or morepreferably 0.37 inches in length and dimension DD may be about 0.28 to0.32 inches, preferably 0.29 to 0.31 inches, or more preferably 0.30inches in length. In another embodiment, dimension CC may be about 130to 170% of dimension DD or more preferably about 140 to 160% ofdimension DD.

Referring to FIGS. 3-4, the base may also include one or more spikes 48extending up from the base. In one embodiment, a line of posts or spikes48, are located on a line between front wall 41 and back wall 46, onboth sides of axis Y. The line of posts or spikes 48 may be generallyparallel to each other and to the longitudinal axis Y or at an angle of,e.g., 1-45° to the longitudinal axis Y. The spikes 48 may extend up fromthe surface of the base or from capture elements running generallyparallel to each other and to the longitudinal axis Y or at an angle of,e.g., 1-45° to the longitudinal axis Y, on both sides of axis Y betweena front wall 41 and a back wall 46.

Referring to FIG. 1, the base 26 may have two squeezing arms 50 oroptionally the base 26 may have one arm 50 that is resilient andflexible and a second arm 50 which is generally fixed and rigid. Thebase 26 may also have a hinge block 62 located on the base 26 at anopposite end from the squeezing arms 50. The squeezing arms 50 areflexible and have latching elements 52 and sidewalls 57. An angledsurface 56 may be provided at the end 54 of each of the latchingelements 52 facing the inner surface of a squeezing arm wall 57, withgrip ribs 59 on the outside of each squeezing arm wall 57. As shown inFIG. 3-4, a through hole 66 may be provided, if desired, in the base 26,behind the hinge block 62. An arrow symbol 49 may be printed, molded orotherwise provided on the base 26 and/or the cover 28, running along alongitudinal Y axis, as shown in FIG. 3. The arrow indicates in whichdirection the catheter should be installed into the universal securingdevice 20.

As shown in FIG. 1, the cover 28 has latch holes 70, and hinge pinholes73 located at opposite ends of the cover 28. Ridges 71, each having anangled surface 72, may optionally be provided below the latch holes 70,as shown, e.g., in the embodiment of FIG. 10. As shown in FIG. 2, thecover 28 is connected to the base 26 by a hinge 60. FIG. 1 shows thatthe hinge may be provided by pressing a hinge pin 75 through hingepinholes 73 and through an aligned hinge pin slot 64 which runs throughthe hinge block 62. The hinge pin 75 may have a round diameter and mayinclude one or more, preferably four, raised crush ribs 77 which serveto hold the hinge pin 75 in place by friction after being press fitthrough the hinge pinholes 73 and hinge pin slot 64. The hinge may alsotake various other forms, for example, a hinge may be formed by tongueand groove elements. A hinge may also be formed by a snap fittingmechanism between a latch or snap hinge and snap hinge base. Varioustypes of hinges or pivot joints may be used. Most designs will have ahinge at one side of the device and a latching element at the otherside, with the cover pivoting open and closed. However, an alternativedesign may have a separate snap on cover having a latch or lock elementat either end of the cover.

As best shown in FIGS. 6-7, the cover 28 includes a first opening 83 ina front wall 84 and a second opening 85 in a back wall 86. The cover 28may have one or more bars 80 which run in a direction DL on theunderside of the cover 28, generally parallel to the lateral X axis. Thecenter area of the bars 80 may be recessed compared to the ends of thebars 80 in order to accommodate the height of various catheter fittings.The bars 80 may be connected by one or more capture elements 82 on theunderside of the cover 28. The capture elements 82 may be generallyparallel to each other and to the longitudinal Y axis, or at an angleof, e.g., 1-45° to the longitudinal axis. The ends of the captureelement 82 may rest at least partially on the surface of the bars 80.One or more posts or spikes 88 may extend from the capture elements 82.In the design shown in FIG. 7, three spikes 88 are spaced evenly apartand extend up from a center elevated segment 86 on the surface of thecapture element 82. Optionally, the capture elements 82 may run alongthe underside of a cover where the cover has no bars.

Turning momentarily to FIG. 2, the capture element 82 is adapted tocontact and compress catheter fittings of various shapes and sizes suchas catheter fitting 32, e.g., by compressing the wings and/or body of acatheter fitting 32 once the catheter fitting 32 is placed onto the base26 within the locating elements 40 and the cover 28 is attached to thebase 26 in a closed position. Capture elements 82 may be solid or springmolded as leaf springs or foam springs. Capture elements 82 may also bean elastomer. The surface of a capture element 82 may optionally beprovided with cones or serrated teeth to assist with compression andgripping of a catheter fitting 32. A single capture element 82 ormultiple capture elements 82 may be used. In the specific design shownif FIG. 2, two capture elements are provided.

Referring again to FIGS. 2 and 4, in use, after the catheter has beeninserted into the patient, the skin at the securement site is preferablycleaned. The catheter fitting 32 is then placed into or onto the base26, within the locating elements 40. The cover 28, which is attached tothe base 26 via the hinge 60, can be closed down, by pivoting about theends of the hinge pin 75 positioned inside the hinge block 62, over andonto the catheter fitting 32. The curved end wall 42, elbow 44 andsemicircular trough 45, all serve to center and align the cover 28 asthe cover 28 is moved down and over the front wall, onto the base 26,and into the closed position. The outside surface of the curved end wall42, elbow 44 and semicircular trough 45 may abut against the innersurface of the front wall 84 of the cover 28 as the cover 28 moves downand into the closed position. Also, a raised post which may be locatedatop one or more elbows 44 may also help align the cover 28 as it closesonto the base 26, and it too may optionally abut against the innersurface of the front wall 84 of the cover 28 as the cover 28 moves downand into the closed position. Also, one or both of the posts 47connected to a back wall 46 may serve to center and align the cover 28as the cover 28 is moved down and over a back wall 46 and the first andsecond posts 47. The first and second posts 47 and back walls 46 mayabut against the inner surface of the cover 28 as the cover 28 movesdown and into the closed position. These alignment features help toproperly locate the cover on the base as the cover is closed.

In a closed position (as shown in FIG. 9), the top end 78 of the cover28 attaches to the base 26 within the squeezing arm walls 57. The latchholes 70 in the front wall 84 and back wall 86 of the cover 28 engagethe latching elements 52 on the squeezing arms 50. This facilitates thesecure attachment of the cover 28 to the base 26, placing the securingdevice 20 in a closed position. The cover 28 rests on the flat andcontoured outer areas of the base 26, around the front wall 41 and backwalls 46 (not shown because enclosed by cover), and on the flat area ofthe squeezing arms 50.

In a closed position, the spikes 88 on one or more capture elements 82may compress down on the wings and/or body of the catheter fitting 32.The wings of the catheter fitting 32, which are generally somewhatflexible or compliant, are thereby pinched or held between the spikes 88of capture element 82 and the spikes 48 extending up from the surface ofthe base 26. The spikes 88 and the spikes 48 are located to grip andcompress the wings and/or body of the catheter fitting. As shown if FIG.8, the spikes 88 and spikes 48 are preferably about 0.04 inches inheight and some vertical space may exist between the tips of the spikes88 and the spikes 48 when the cover 28 is in the closed position. Thespikes 88 may also be slightly offset by 0.02-0.12 inches to the insideof the spikes 48, i.e., toward the arrow 49. The spikes 88 may also besimilarly offset to the front of the spikes 48, as indicated by arrow49. This applies a pinching or bending effect on the wings of thecatheter, in addition to compression. By having the top and bottomspikes offset from each other, the device 20 can better secure cathetershaving wings of varying thickness.

The capture elements 82 thereby secure a catheter fitting 32 withinsecuring device 20 by preventing substantial movement of catheterfitting 32 in an axial, side-to-side, back-to-front, up and down androtational direction. The capture element 82 may be resilient andflexible, capable of holding and griping catheter fittings of variousthicknesses. The capture element 82 may also be solid. The cover 28 maybe used in conjunction with a base 26, having locating elements 40 andspikes 48, for securing a catheter fitting.

In another embodiment, the cover 28 may be used in conjunction with abase 26 for compressing and holding a catheter body on a patient. Thebase may or may not have locating elements. In use, this embodimentwould function by placing a catheter on a base 26 and compressing orpinching the catheter body between an underside surface of a cover 28,e.g., against capture elements 82 or any part of the underside of thecover, and a top surface of the base with sufficient force to hold orrestrain the catheter in place without substantial movement in variousdimensions relative to the base and cover, e.g., axial, side-to-side,back-to-front, up and down and rotational. This arrangement, forcompressing a catheter body of various shapes and sizes between a coverand base could be performed with any of the additional embodimentsdescribed below as well.

Referring again to FIGS. 2 and 4, as the top end 78 of the cover 28 ismoved down onto the base 26 from an open position to a closed position,the angled surfaces 56 on the ends 54 of the latching elements 52 engagethe inner surface of the front wall 84 and back wall 86, below the latchholes 70 on the cover 28. Alternatively, the angled surfaces 56 on theends 54 of the latching elements 52 may engage the angled surfaces 72 ofridges 71, positioned below the latch holes 70 on the cover 28, e.g., asshown in the embodiment of FIG. 10. The latching elements 52 aresomewhat resilient and can flex slightly under load in the longitudinaldirection (along axis Y as shown in FIG. 1). As a result, as the cover28 is moved down into engagement with the base 26, the latching elements52 flex slightly inwardly toward each other. The angled surfaces 56 ofthe latching elements 52 and the inner surface of the front and backwalls 84, 86 below the latch holes 70 on the cover 28 or the angledsurfaces 72 of the ridges 71 slide against each other and pass by eachother. The latching elements 52 then flex back to near their originallongitudinal positions, forcing the ends 54 of the latching elementsthrough the latch holes 70 in the cover 28 and locking the cover 28 ontothe base 26. The catheter securing device 20 is then attached to thepatient at the prepared securement site, usually via an adhesive pad.The securing device 20 then prevents virtually any movement of thecatheter fitting 32 and adjoining catheter 30 within the securingdevice.

The catheter 30 may be removed by squeezing the squeezing arms 50together, towards each other. One or both of the squeezing arms 50 maybe resilient and flexible such that they may flex in the longitudinaldirection. The squeezing arms 50 may be squeezed together by applying aforce in the longitudinal direction, generally on the area of the gripribs 59 located on the outer surface of the squeezing arm walls 57.Squeezing also causes the latching elements 52 on the squeezing arms 50to move longitudinally toward each other, resulting in the ends 54 ofthe latching elements 52 moving back through and out of the latch holes70. The latching elements 52 move toward each other such that the cover28 can be lifted away from the latching elements 52. The angled surface56 and angled surface 72 and/or inner surface of the cover 28 pass byeach other as the cover 28 is pivoted up and off of the base 26.

The securing device described above may be attached to a patient in avariety of ways. As shown in FIG. 1, a base 26 may be attached to a pad162 which is flexible to conform to the patient's arm or other site. Thepad could be a hydro colloidal pad. The specific pad shape and size isnot essential and various alternatives may be used. In FIG. 1, the pad162 is generally oval or round and it can also be a small footprint of abase 26. The back side of the pad 162 preferably has one or morepeelable strips over an adhesive layer or surface. The peel strips maybe removed from the back of the pad 162, and the pad placed onto aprepared securement site. A cut out 164 may be provided at the front ofthe pad 162 to allow the base 26 to be closer to the incision orcatheter entry point. Alternatively, the securing device may be affixeddirectly to a patient by applying adhesive tape around the device andagainst the patient's arm or other site.

FIG. 10 shows another embodiment 90 of a universal securing device.Securing device 90 has a base 96 and a cover 98. In this embodiment, asshown in FIG. 11, the locating elements extending up from the base 96are locating pegs 100 and each peg is surrounded by a ridge 102 at thebase of the peg.

As with the locating elements 40 shown above in FIG. 3, a first backlocating peg 103 may be separated from a second back locating peg 103 bya dimension CC, while a first front locating peg 101 may be separatedfrom a second front locating peg 101 by a dimension DD, as shown in FIG.11. In one embodiment dimension CC may be greater than dimension DD. Inanother embodiment dimension CC may measure about 0.35 to 0.39 inches,preferably 0.36 to 0.38 inches, or more preferably 0.37 inches in lengthand dimension DD may be about 0.28 to 0.32 inches, preferably 0.29 to0.31 inches, or more preferably 0.30 inches in length. In anotherembodiment, dimension CC may be about 130-170% of dimension DD or morepreferably about 140-160% of dimension DD.

In addition, in FIG. 11, the locating pegs 100 positioned closest to thehinge block 62 and located above the arrow 49, may be connectedgenerally horizontally by a capture element 104. The locating pegs 100located below the arrow 49 and closest to the latching arms 50 may alsobe connected generally horizontally by a capture element 104. Spikes 106may extend up from the surface of the capture elements 104. Asemicircular trough 108, running generally parallel to the lateral axisX of the base 96 and positioned in front of the locating pegs 100 (asindicated by the arrow 49) may also extend up from the base 86. Thespikes may optionally extend up from the surface of the base 86 in anembodiment without capture element 104.

As shown in FIGS. 12-13, the cover 98 includes a first opening 110 in afront wall 114 a and a second opening 112 in a back wall 114 b. As bestshown in FIG. 12 and with reference to the base 96 in FIG. 11, providedon the under side of the cover 98 are locating pegs 100 a which arecapable of fitting inside locating pegs 100 on base 96. The locatingpegs on cover 98 include a front pair 101 a and back pair 103 a oflocating pegs, each with ridges 102 a as well at least one captureelement 104 a running between the locating pegs on the underside of thecover 98 arranged in a configuration that generally mirrors theconfiguration of locating pegs 100 and capture element 104 on the base96. Spikes 106 a may extend up from the capture elements 104 a. Thefront pair 101 a and/or back pair 103 a of locating pegs may bepositioned in between or outside bars 80, which are located on theunderside of the cover 98 and run generally parallel to the lateral Xaxis (shown in FIG. 12). The capture elements 104 and 104 a may bespring molded. Also, if desired, at least one locating peg 100 a may bepositioned at least partially on the surface of a bar 80.

In one embodiment, the locating pegs 100 a on the cover are connected bya capture element 104 a which is positioned at an angle of about 1-45°to a longitudinal Y axis across the underside of the cover 98 andlocating pegs 100 on the base 96 are connected by a capture element 104which is positioned at an angle of about 1-45° to a longitudinal Y axisacross the base.

The securing device 90 shown in FIGS. 10-15 operates in much the sameway as the securing device 20, shown in FIGS. 1-9 and described above.Additionally, as cover 98 closes onto a catheter fitting 116 (or othercatheter fittings of various sizes) which is positioned between thelocating elements and latches onto base 96, locating pegs 100 a mayalign with and engage locating pegs 100 as shown in FIGS. 14-15. Thishelps prevent cover 98 from shifting or moving, making the latchingmechanism between latching elements 52 and latch holes 70 even morereliable. Also, spikes 106 and 106 a are configured and arranged similarto the spikes in the embodiments of FIGS. 1-9 and described above. Thus,spikes 106 and 106 a help compress and grip catheter fittings of variousshapes and sizes such as catheter fitting 32, (e.g., by compressing thebody and/or wings of the catheter fitting) securely holding the catheterfitting 32 in place and preventing substantial movement of the fittingin various dimensions as described above with respect to FIGS. 1-9.

In another embodiment, as shown in FIG. 48, a securing device 420includes a base 426 and a cover 427. The cover 427 may be removably orpermanently attached to the base 426 by a hinge 450. The base 426includes an opening 430 configured to receive a retention plate 428 anda support plate 429 or seal plate or other structure suitable forholding or supporting the retention plate. The base 426 may include oneor more restraining elements 431 attached to the top surface of the base426 and extending at least partially over the opening 430. Therestraining elements 431 may be, e.g., pins, pegs, bars, walls,extensions, etc. The base 426 may optionally include one or morealignment pins 446 extending up from the top surface of the base 426 tohelp guide and align the cover 427 over a catheter or catheter fittingpositioned on the retention plate 428 during closing.

The cover 427 may be temporarily or permanently coupled to the base 426in a variety of ways. For example, as shown in FIG. 48, the base mayinclude a hinge 450 which is configured to receive a pin 475. The pin475 is inserted through a pin hole 471 in the cover 427 and through thehole in the hinge 450, thereby attaching the cover 427 to the base 426such that the cover may rotate or pivot about the pin 475. In anotherembodiment, as shown in FIGS. 51-53, the base 426 may include a groove452 and bar 453, and the cover 427 may include a tongue 451 or any otherstructures suitable for connecting the cover 427 to the base 426. Thetongue 451 may be substantially arc shaped or may have any other shapesuitable for attaching to the bar 453 or other structure on the base426, or for inserting into the groove 452. In one embodiment, the arcshaped tongue 451 may have a perimeter greater than 180°. The tongue 451may be engaged, connected, or snapped onto the bar 453 and/or pressedinto the groove 452. The tongue 451 may rotate or pivot about the bar453 or through the groove 452 when the cover 427 is moved into a openedor closed position, providing a type of hinge. Optionally, the tongueand groove or bar may provide a non pivotable or non rotatableconnection.

Optionally, as shown in FIG. 51, a restraining arm 454 may extend fromthe base and be positioned near the bar 453 and groove 452, in betweenthe opening 430 and the bar 453 and groove 452. A corresponding tab 455may extend from the tongue 451. As the cover 427 is rotated into anopened position, the tongue 451 may contact the restraining arm 454,thereby stopping the rotation of the cover 427, and preventing thetongue 451 from being disengaged from the bar 453. The restraining arm454, which may be flexible or resilient, can be flexed in a horizontaldirection allowing the tab 455 to slide past the restraining arm 454 andthe tongue 451 may then be disengaged from the bar 453. In otherembodiments, the restraining arm 454 may be rigid and/or the cover 427and base 426 may be permanently connected.

The base 426 may include one or more latching elements 480 positioned onthe base 426 at an end generally opposite from the hinge 450 or othercoupling structure. In one embodiment, as shown in FIG. 48, the latchingelements 480, which fit into receiving holes 481 on the cover 427, maybe connected to one or more squeezable arms 482 and operate to attachand detach the cover 427 to and from the base 426, as described above,e.g., in the embodiments of FIGS. 1-15. The cover 427 and/or base 426may optionally include a latch or any other suitable attachment orfastening structure or mechanism for removably fastening or attachingthe cover 427 and base 426 together in the closed position without theuse of squeezable arms.

As shown in FIGS. 48-49, the retention plate 428 preferably has aperimeter which is smaller than the perimeter of the opening 430 suchthat there remains some clearance between the perimeter of the retentionplate 428 and the perimeter of the opening 430 when the retention plate428 is positioned in the opening 430. The clearance space may beprovided around the entire perimeter of the retention plate 428, aroundat least a portion of the retention plate 428 perimeter, or optionallyno space at all may be provided around the retention plate 428 perimeterif the retention plate 428 is sized to fit against the perimeter of theopening 430. The clearance or space allows for movement of the retentionplate 428 in a variety of dimensions, including, e.g., along thelongitudinal Y axis, along the lateral X axis, or vertically. In anyembodiment the retention plate 428 may be a single piece, or it may bemade up of two or more separate pieces as shown in FIG. 51. Optionally,the retention plate 428 may be positioned at least partially in theopening 430. In other embodiments, the retention plate 428 may bepositioned slightly above or below the opening 430.

Optionally, extending up from the retention plate 428 are locatingelements. In the illustrated embodiments shown in FIGS. 48, 49 and 51,the locating elements positioned at the front of the retention plate 428(as indicated by the arrow 449) each include a wall 441 connected to anelbow 442, which is connected to a generally semicircular receiving area443. This receiving area 443 may optionally be any other shape or designsuitable for receiving a catheter, catheter fitting or other medicaldevice. The locating elements positioned at the back of the retentionplate 428 are in the form of locating pegs 444, and they may optionallyhave ridges or ledges 445 extending therefrom. Optionally, the front andback locating elements may be in the form of, e.g., walls, ridges, pegs,pins or any combination of these. Optionally, the locating elements maybe positioned substantially symmetrical, side-to-side about thelongitudinal axis of the securing device 420 or centerline Y, orarranged or positioned in any manner suitable to hold, position orrestrain catheters or catheter fittings of various shapes or sizes toprevent substantial movement of the catheters or catheter fittings inone or more directions. Optionally, the locating elements may beconfigured, arranged, or positioned relative to each other, as detailedin the embodiments discussed above and below, to accommodate, hold, orrestrain catheters or catheter fittings of various shapes or sizes.

As shown in FIG. 48, the support plate 429 preferably has a perimeterthat is larger than the perimeter of the retention plate 428 butslightly smaller than the perimeter of the opening 430 such that thesupport plate 429 may be inserted into the opening 430. The retentionplate 428 is inserted into the opening 430 from the back side of thebase 426 and the restraining elements 431 prevent the retention plate428 from falling through the front side of the base 426 (See FIGS.49-50). The support plate 429 may be inserted at least partially intothe opening 430 after the retention plate 428 has been inserted. Thesupport plate 429 may be press fit into the opening 430 and held inplace by friction to prevent the retention plate from falling throughthe back side of the base 426. Optionally the support plate 429 may beaffixed within the opening 430 or to the base 426 by welding, gluing,insert molding, or by any other method suitable for temporarily orpermanently attaching the support plate 429 within the opening or to thebase 426. Alternatively, the support plate 429 may have a perimeterlarger than the opening 430 and may be affixed to the bottom of the base426 around the opening 430.

The top surface of the support plate 429 may optionally be substantiallyflexible, cushioned, resilient or constructed in any manner suitable toallow for movement of the retention plate 428 in a dimension up or downor vertically, e.g., relative to the base 426 or securing device 420.For example, such movement is permitted when the support plate 429 isattached to the base 426 and the retention plate is positioned on top ofthe support plate 429 and below the restraining elements 431.Accordingly, the retention plate 428 is substantially free floating ormovable, which allows the securing device 420 to accommodate cathetersor catheter fittings of various shapes, sizes, or thicknesses. Indeed,to secure a catheter in the securing device 420, a catheter is placedonto the retention plate 428 and the cover 427 is closed down over thecatheter or catheter fitting. In one embodiment, the underside of thecover 427, capture elements 460, or pressure pins 461, spikes or postsmay contact, compress, hold, restrain, or apply a downward force on thecatheter or catheter fitting. As a result, the retention plate 428 mayalso be forced downward against the top surface of the support plate 429allowing the securing device 420 to hold, restrain or accommodatecatheters or catheter fittings of various shapes, sizes, or thicknesses.In another embodiment the support plate 429 may be substantially rigidor the retention plate 428 may be substantially flexible, or both may besubstantially rigid or flexible.

Furthermore, the securing device 420 may be attached to a patient in avariety of ways. For example, an adhesive pad, as described in the aboveembodiments or an adhesive tape may be used for attaching the medicaldevice to a patient. For example, an adhesive pad may optionally beattached to the base 426 or the support plate 429. Optionally, any othersuitable attaching method or structure may be used.

In another embodiment as shown in FIG. 54, a securing device 520configured to receive a catheter or catheter fitting, e.g., an IV(intravenous) catheter, IV hub, IV luer, IV adaptor or any other similarmedical tubing or medical accessory or tubing as well as other cathetersor catheter fittings for use in other applications, includes a base 526and a cover 527. The cover 527 may be removably or permanently attachedto the base 526 by a hinge. The base 526 may optionally include one ormore alignment pins 546 extending up from the top surface of the base526 and positioned generally near the perimeter of the base 526 to helpguide or align the cover 527 over a catheter 510 or catheter fittingpositioned on the base 526 during closing of the securing device 520.The alignment pins 546 may optionally serve to receive, capture, orrestrain flanges, wings or other parts of a catheter or catheter fittingin certain embodiments.

Optionally, the base 526 may include one or more locating elements,e.g., locating pegs 544, extending up from the surface of the base 526.The locating elements may take on a variety of forms, e.g., walls,ridges, pegs, pins or any combination of these. The base 526 may alsoinclude a receiving area 547. The receiving area 547 may be any shape ordesign suitable for receiving a catheter, a catheter fitting, e.g., acatheter hub 511, or any other medical device. Optionally, the receivingarea 547 may have a generally oval or rectangular shape. The receivingarea 547 may also be indented, recessed, sloped, or generally concave.In one embodiment, the receiving area 547 may be generally contoured tomatch the shape of a catheter hub.

In the embodiment shown in FIG. 54, the receiving area 547 is defined bya plurality of locating pegs 544, arranged in rows on either side of thereceiving area. The locating pegs 544 may optionally have ridges orledges extending therefrom. In one embodiment, the locating pegs 544 arepositioned from the back of the base 526 to the front of the base 526(as indicated by the direction of the catheter 510) in two rows forminga generally V-shaped or tapered arrangement suitable for receiving astandard catheter hub. In another embodiment, the locating pegs 544 maybe arranged in rows running substantially parallel to the longitudinal Yaxis of the device 520. Optionally, the locating pegs 544 may bepositioned substantially symmetrically or offset, side-to-side about thelongitudinal axis of the securing device 520 or offset, side-to-sidefrom each other. They may also take on a linear arrangement or an offsetstaggered arrangement, longitudinally along the base 526. The locatingpegs 544 may be arranged in any manner suitable to hold, position orrestrain catheters or catheter fittings of various shapes or sizes toprevent substantial movement of the catheters or catheter fittings inone or more directions or dimensions, e.g., in an axial, side-to-side,back-to-front, up and down or rotational directions.

The base may also include two or more front locating pegs 548 and/or twoor more back locating pegs 549 for receiving, capturing, or restrainingthe flanges 512, wings or other parts on a catheter or catheter fitting.The front and back locating pegs, 548, 549 may be spaced apart,side-to-side, by various distances to receive flanges, wings, or hubs ofvarious shapes or sizes to help prevent movement of the catheter orcatheter fitting in the longitudinal or lateral direction. Optionally,any of locating elements may be configured, arranged, or positionedrelative to one another, as detailed in the embodiments discussed aboveand below, to accommodate, hold, or restrain catheters or catheterfittings of various shapes or sizes.

In the embodiment shown in FIG. 54, the base 526 may be contoured tomatch the anatomy of a patient, e.g., the arm, leg, or scalp, dependingon where a catheter or other medical tubing is to be inserted and wherethe securing device 520 is likely to be placed. The base 526 ispreferably shaped and configured to allow the maximum amount of catheterfitting or needle exposure or extension beyond the perimeter of thebase, while still securing the catheter fitting in place. Thus, luerlocks and other connectable components may be conveniently attached toan end of a catheter fitting, such as a catheter hub, and the needle orcatheter can be properly inserted into a patient. The thickness of thebase 526 may optionally taper in the longitudinal direction, graduallydecreasing from the back to the front of the securing device 520. Thebase 526 may slope generally in the longitudinal direction, from theback to the front of the securing device at an angle suitable tofacilitate insertion of a needle or catheter into a patient. In oneembodiment, the angle may be about 4°-10° or 5°-9° or 6°-8°.Accordingly, a catheter fitting or catheter may be positioned on top ofthe sloped or angled base and be directed toward the patient at an anglethat allows for optimum flow, delivery, or drainage of any fluid to andfrom a patient.

As shown in FIGS. 54 and 56, the cover 527 may include a first opening567 in a front wall 565 and a second opening 568 in a back wall 566through which the ends of the catheter or catheter fitting extend.

In one embodiment, the cover 527includes one or more receiving openings 562 located generally in thecenter of the cover 527 for receiving tabs or other extensions on acatheter fitting (e.g., a hub) to help hold the catheter fitting inplace and prevent substantial rotational, longitudinal, or lateralmovement of the hub.

One or more tabs 564 optionally extend from the underside of the cover527 and may be positioned in between or adjacent to one or morereceiving openings 562. The tabs 564 may be configured to extend inbetween corresponding tabs or into indents on a catheter fitting oragainst the fitting to help restrain, grip, or hold the catheter fittingin place or against the base 526. One or more contact ridges 563 mayextend from the underside of the cover 527 and may be generally arcshaped or have any shape suitable to engage a catheter fitting andrestrain, grip, or hold the catheter fitting against the base 526. Thecontact ridges 563 are preferably positioned on the underside of thecover 527 in between a receiving opening 562 and the second opening 568or first opening 567. Preferably, the receiving openings 562, contactridges 563, and tabs 564 are in alignment with the first opening 567 andsecond opening 568 generally along the longitudinal Y-axis of the cover527.

The cover 527 may also have one or more bars 569 which run in adirection generally parallel to the lateral X-axis, along the undersideof the cover 527. The bars 569 may optionally run at an angle of, e.g.,1-45 degrees from the lateral X axis. The bars 569 provide support orstiffness to, or minimize distortion or deflection of, the cover 527when it is moved into a closed position in which it applies pressure toa catheter fitting on the base 526. In the embodiment shown in FIGS. 54and 56, the bar 569 runs parallel to the lateral axis and is positionedadjacent to the front opening 567, while the contact ridge 563 ispositioned adjacent to the back opening 568. The center area of the bar569 may be generally recessed to accommodate the heights of catheterfittings having various shapes and sizes.

The front and back openings 567, 568 of the cover 527 are configured toallow passage of catheters and catheter fittings of various shapes andsizes, while assisting with alignment and securement of the same.Preferably, the front and back openings, 567, 568 are contoured toaccommodate catheter fittings having various shapes. The front and backopenings 567, 568 are also of sufficient size such that attachments,such as luer locks, will abut against the outer perimeter of theopenings to further prevent longitudinal movement or pistoning ofcatheters and catheter fittings in the longitudinal direction. As shownin FIGS. 54 and 56, the center area of the cover 527 may be generallycontoured, arched, or raised relative to the remainder of the cover 527to accommodate catheter fittings of various sizes. Preferably, thecenter area of the cover 527 is angled in a manner that corresponds tothe angle or slope of the base 526. In one embodiment, the angle isabout 4°-10° or 5°-9° or 6°-8°. Accordingly, a catheter fitting orcatheter may be restrained in the securing device 520 in a manner thatdirects the needle or catheter toward the patient at an angle thatallows for optimum flow, delivery, or drainage of any fluid to and froma patient.

Furthermore, the cover 527 may include one or more indents 572 in thefront or back walls 565, 566 of the cover for receiving the alignmentpins 546 and aligning the cover 527 on the base as the cover 527 movesinto or rests in the closed position.

Extending up from the back or rear area of the retention plate 528 maybe one or more tabs 533. In one embodiment, a catheter fitting, e.g., acatheter hub, can be pressed onto or rest on top of the tabs 533, whichmay also extend in between corresponding tabs extending from thecatheter fitting or into indents on the catheter fitting to help hold oralign the catheter fitting onto the retention plate 528. The tabs 533may be of various heights or sizes. Preferably, the tabs 533 arearranged side-by-side along the longitudinal axis, with each set of tabs533 increasing in height from the front of the retention plate 528toward the back of the retention plate 528 in order to support acatheter fitting at a preferred angle for directing a needle or catheterinto a patient's skin. Optionally, the retention plate 528 may be angledor sloped as described above to have a similar effect. A contact ridge563 may also extend up from the back of the retention plate 528. Theabove arrangements of walls, tabs 533, or contact ridge 563 may also beused with a non-floating base like the one described above in FIGS.54-56.

The cover of the embodiment shown in FIGS. 59 and 60 may include one ormore receiving openings 562 or bars 569. Extending form the bar 569 maybe a contact ridge 563 for contacting a catheter hub or other catheterfitting and applying pressure to the catheter hub when the device is inthe closed position. The cover 526 can rotate down onto the base by ahinge mechanism and latch into a closed position as described in theembodiments above. Optionally, the cover may be snapped onto the basefor attachment.

In another embodiment, as shown in FIGS. 61 and 62, the securing device521 may include a base 526 and a cover 527. One or both of the surfaceof the base and the underside of the cover may be smooth or flat. Thebase or cover may apply pressure to the catheter fitting when thesecuring device is in the closed position, thereby holding or securingthe catheter or catheter fitting in place and preventing movement invarious directions or dimensions. Optionally, one or more locatingelements 540 may extend up from the base 526 to receive, hold, or alignthe catheter or catheter fitting in place or to hold the flange or wingsof a catheter fitting and prevent longitudinal or lateral movement ofthe fitting. Alignment walls or bars may also extend up from the base.The front walls of the base 526 and cover 527 may be generally arched orcurved such that the front end of the catheter fitting remains in closeproximity to the patient. Furthermore, the floating base configurationdescribed above with reference to FIGS. 59 and 60 may be implemented inany of the embodiments shown in FIGS. 54-58 and 61-62.

In any of the above embodiments, the base 526 may be permanently orremovably attached to the cover 527. The cover 527 may rotate onto andoff of the base using any of the hinge mechanisms or snappingattachments described above. Additionally, as shown in FIGS. 55 and 56,the cover 527 may include an inner cam 557 or tongue and generallyrounded outer cams 558. The inner cam 557 is attached to a bar 553around which it may pivot or rotate. The bar 553 serves to center,align, stabilize, or locate the cover 527 on the base 526 to preventsubstantial side-to-side movement as it rotates. As the cover 527rotates, the outer cams 558 engage the corresponding rounded followersurfaces 559 on the base 526 which also serves to center, align,stabilize, or locate the cover 527 as it rotates. A tab 555 extendingfrom the inner cam 557 may engage the ridge 556 on a restraining arm 554which extends from the base to prevent over rotation of the cover 527 ordetachment of the cover 527 when it is in the open position.Overrotation or removal may be performed by applying additional force toslide the tab 555 past the ridge 556.

In an embodiment of the securing devices described above, the securingdevice may limit the axial motion of an IV Hub or other catheter fittingor catheter to +/−1.5 mm. The securing device may secure an IV Hub towithin its travel limit when subjected to a pull force of up to about 3lbs in any direction on any one of its tubes or catheters. The securingdevice may not open when any one of the tubes or catheters is pulledwith a force up to about 3 lbs in any direction and the cover shallremain secured with up to about 5 lbs of applied force in any direction.An adhesive Tricot may be bonded to the bottom surface of the securingdevice for attachment to the patient's skin and the base shall notseparate from the adhesive with less than about five lbs of force. Thecover may optionally be clear to allow a user to view the IV hub oncethe device is closed. The base may also be clear. The securing devicemay have an arrow molded or printed on the base or cover to indicate thedirection of flow toward the catheter distal end and aiding in orientingthe catheter when it is put in place. The cover may open with a maximumapplied force from the user of about 5 lbs to the tab. The cover mayclose with a maximum applied force from the user of about 4 lbs.

In another embodiment, as shown in FIGS. 63 and 64, a securing device610 includes a base 611. A receiving area 612, which may besubstantially arc shaped, semi-cylindrical, or generally contoured toreceive or hold a catheter hub or other catheter fitting, may bepositioned on the center of the base 611. The receiving area 612 may beflexible or resilient to accommodate various catheter fittings. Thereceiving area 612 extends generally along the longitudinal Y axis andis bordered on either side by restraining walls which run generallyparallel to the longitudinal Y axis. Preferably, one restraining wall613 is fixed and the other is movable, forming a swinging gate 613 a.The fixed wall 613 may optionally be a separate piece or an extension ofthe receiving area 612. The swinging gate 613 a may open by applyingpressure to a deflectable, resilient, flexible, or spring loaded tab 616or other latching mechanism to disengage the tab 616 from the swinginggate such that the swinging gate 613 a may pivot or rotate in thelateral direction, away from the receiving area 612. A catheter orcatheter fitting may then be positioned onto the inner surface 617(shown in FIG. 63) of the receiving area 612 which faces away from apatient when the securing device is positioned on a patient. In oneembodiment, the inner surface 617 of the receiving area 612 may includeone or more receptacles 615 (shown in FIG. 63) or indents for receivingtabs or other extensions on a catheter hub or other catheter fitting tohold the catheter in place on the securing device 610 and preventsubstantial longitudinal movement or movement in other directions ordimensions.

Once the catheter hub is in place, the swinging gate 613 a is rotatedback toward the receiving area 612. The swinging gate engages the tab616 and slides past the tab 616, which can flex slightly under the loadand then return to its original position, latching or locking theswinging gate 613 a into place and securing the catheter fitting withinthe receiving area 612. In another embodiment, the securing device maybe designed such that the base 611 includes two parts extending fromeither side of the receiving area 612, where the bottom surface of thereceiving area and/or the bottom surface of the base 611 are attached toan adhesive pad or a patient. Optionally, the base 611 is contoured tothe anatomy of a patient or is slightly resilient or flexible to form tothe anatomy of a patient. A pad 605 may be attached to the underside ofthe base 611 to adhere the device to a patient.

In another embodiment, as shown in FIGS. 65-67, a securing device 630includes a base 631. Extending up from the base are one or more tracks633 which run parallel to the lateral X axis. The tracks 633 areseparated by a receiving area 632 for receiving catheters and catheterfittings of various shapes or sizes. One or more movable or slidableclamps 641 are connectable to the tracks 633. The top surface of thetracks 633 include ribs 634. The underside of the clamps 641 include oneor more teeth 636 positioned within a recessed indent 639. The indent639 runs along the lateral X axis and is configured to receive a track633. The clamps 641 may be attached to the tracks 633 by inserting atrack 633 into the indent 639 of the clamp 641, thereby allowing theteeth 636 to engage the ribs 634.

The top surface of the clamp 641 includes a fixed tab 638 and a push tab637. The push tab 637 in connected to a retention wedge 640 whichextends from the underside of the clamp 641 and is spring loaded orflexible or resilient such that it is forced or pressed against thetrack 633, allowing the clamp 641 to be held in a fixed position. Thepush tab 637 may be pushed toward the fixed tab 638 in the longitudinaldirection, which causes the retention wedge 640 to flex away from thetrack 633, at which time the clamp 641 may be moved or slid along thelateral X axis either away from or toward a catheter fitting positionedwithin the receiving area 632. The ribs 634 and teeth 636 interact witheach other to create a ratchet like mechanism, which provides differentsettings for positioning, locking, or holding the clamps 641 in relationto each other. The clamps may be adjusted or restricted to each rib 634or notch on the track 633 to accommodate catheter fittings of differentshapes or sizes.

In operation, one or more clamps 641 are pushed or slid toward eachother along the tracks 633 toward a catheter fitting to clamp or holdthe catheter fitting in place. The retention wedge 640 or ratchetmechanism of the ribs 634 and teeth 636 may hold or lock the clamps 641in place and restrict further movement unless desired. In the closedposition, contact bars 635 apply pressure to the catheter or catheterfitting, e.g., catheter hub, to securely hold the catheter or catheterfitting in place and prevent movement in various dimensions ordirections. Likewise, one or more clamps 641 may be moved or slid alongthe tracks 633 away from each other in order to release the restrainedcatheter fitting. Also, the clamps 641 include slits 642 for receivingtabs or other extensions on a catheter hub or catheter fitting when theclamps 641 are in the closed position to prevent longitudinal, lateral,or other types of movement. Further, flanges or wings on a catheterfitting positioned within the receiving area 632 may abut against thetracks 633 to further prevent movement of the catheter or fitting in thelongitudinal direction. In any of the above embodiments, the base may begenerally V-shaped, see e.g., FIG. 65, in order to position the hub orcatheter fitting in close proximity to the patient to facilitate ease orconvenience of use.

In FIG. 68, another variation of the embodiments in FIGS. 65-67 isshown. Here, the securing device 630 operates in a similar manner asdescribed above, however the design of the securing device is varied.The push tab 637 and fixed tab 638 are oriented in planes that runsubstantially parallel to the plane of the base 631, rather than inplanes that are substantially perpendicular to the base. This provides asecuring device with a lower overall profile. The push tab 637 operatesby being pushed against the fixed tab 638 in order to flex the retentionwedge or teeth on the underside of the clamps away from the track andribs, thereby allowing the clamps to be slid or ratcheted along thetracks into an opened or closed position.

In another embodiment, as shown in FIGS. 69 and 70, a securing device660 includes a base 661. The base includes a track 663. Positioned onthe base 661 are one or more clamps. One or more of the clamps may bemovable. In one embodiment, there is a movable clamp 668 and a fixedclamp 668 a. Extending from the movable clamp 668 in a direction towardthe fixed clamp 668 a is a ratchet arm 665, which is positioned withinthe track 663 The end of the ratchet arm 665 may have ribs 664 on itsupper surface. Restraining walls 669 are positioned on the inner surfaceof the clamps to grip or hold catheters or catheter fittings of varioussizes in place.

In operation, the movable clamp 668 is pushed toward the fixed clamp 668a such that it rotates about a pin 667 or other suitable rotational orhinge mechanism. As the clamp 668 is pushed, the ribs 664 on the ratchetarm 665 engage teeth or corresponding ribs on the underside of the fixedclamp 668 a. The ratchet arm and clamp move within the track by beingslid or ratcheted toward the fixed clamp 668 a. The clamps, in a closedposition, hold a catheter fitting positioned on the base 661 therebysecuring it in place. The ratchet mechanism may hold or lock the movableclamp 668 in place at different intervals or notches to accommodatecatheters or catheter fittings of various shapes or sizes.

The catheter or catheter fittings are held in place by the restrainingwalls 669 on the inner surface of the clamps. The restraining walls 669may be made of foam or other moldable material which conforms to theshape of the catheter fitting to hold it in place. Teeth, spikes, anytype of capture element, or any material suitable to hold catheterfittings may also extend from or line the restraining walls 669 or innersurface of the clamps to hold or grip various catheter fittings. Torelease the clamps from a catheter fitting, the end of the ratchet arm665 can be pressed down toward the base, thereby disengaging the ribs664 to teeth connection and allowing the movable clamp 668 to slide awayfrom the fixed clamp 668 a.

In another embodiment, as shown in FIGS. 71 and 72, a securing device680 for securing various IV luer locks, J-loop locks, luer locks, andother catheter fittings includes a base 681. Positioned on the topsurface of the base 681 is a first receiving area 682 having asubstantially cylindrical shape with an opening 686. Adjacent to thefirst receiving area 682 is a platform 685 with a second substantiallysmaller receiving area 683 extending from the platform 685. The secondreceiving area 683 is also substantially cylindrical in shape with anopening 687. The second receiving area 683 may include grooves 684 whichare configured to receive or grip a luer lock or other fitting attachedto an IV catheter hub or other catheter or catheter fitting when thecatheter hub is placed within the first and second receiving areas andsecurely held in place to restrict substantial movement of the catheter.Optionally, as shown in FIG. 72, swivel arms 689 may extend from boththe first and second receiving areas 682, 683. The swivel arms 689attach to a ridge 688 along the top of a trunk 690 such that thereceiving areas can rotate or swivel about the ridge 688 or trunk 690.

In another embodiment, as shown in FIGS. 73 and 74, a securing device700 includes a base 701 and two receiving areas 702, 703 havingsubstantially cylindrical shapes which extend from a platform 704. Thesecuring device 700 is suitable to hold or restrain a J-loop lock, luerlock, or other catheter fitting. For example, a J-loop lock or othercatheter fitting may be positioned within the receiving areas 702, 703,and rest on the top surface of the platform 704. An arm 706 of a J-looplock may extend through the space between the two receiving areas and beheld or locked in place within a groove 705 to prevent movement of theJ-loop lock. The arm 706 may be held by a groove 705 positioned anywhereon the end of the receiving area 702 such that the J-loop lock can bepositioned at different angles.

Additional embodiments for securing a J-loop lock, luer lock, or othercatheter fitting are shown in FIGS. 75-77. FIGS. 75 and 76 show asecuring device 710 with a base 712 and a dome 711 extending up from thebase. A J-loop lock can be positioned within the dome 711 such that anarm of the J-loop lock is slid into the side slit 714 and into thegroove 715 to be held or locked into place. A plate 713 (shown in FIG.76) within the dome 711 also serves to restrain a J-loop lock or othercatheter fitting positioned in the dome 711 as the catheter fittingabuts against the plate 713, preventing movement in the longitudinaldirection and locking or holding the catheter fitting in place againstthe plate 713. The dome 711 has an opening on either end to allow forpassage of the catheter. FIG. 77 shows a securing device 720 whichincludes a base 721 and a slidable receiving plate 723 for holding orrestraining a J-loop or other catheter fitting. The J-loop, for example,one made of injection molded hard plastic, can be attached to theretention groove 724 in the receiving plate 723 and the receiving plate723 may be slid onto the base 721 and locked or held to the base 721 bythe flex locks 722.

Another embodiment for securing catheter fittings such as IV catheterhubs of various shapes or sizes is shown in FIG. 78. The securing device730 includes a ring clasp 732 and base flanges 731 extending form thering clasp 732. The ring clasp 732 is made of two halves which can pivotopen and closed about a center joint 733. A first half 734 of the ringclasp 732 has a ridge 736 which engages a locking area 737 on the secondhalf 735 of the ring clasp 732. This locking mechanism serves to holdthe ring clasp 732 in the closed position when a catheter or catheterfitting is positioned therein, in order to prevent movement of thecatheter or securely hold it in place. Optionally, the locking mechanismmay operate by snapping a resilient or flexible ridge 736 into thelocking area 737.

Furthermore, any of the securing devices may be attached to a patient ina variety of ways. For example, an adhesive pad, as described in theabove embodiments or an adhesive tape may be used for attaching thesecuring device to a patient. For example, an adhesive pad mayoptionally be attached to a base or to a support plate. Optionally, anyother suitable attaching method or structure may be used.

Another embodiment of a securing device 124 is shown in FIGS. 16-20. Asbest shown in FIG. 17, grooves 130 are provided on cover 128 which helpmake the cover more flexible. A latch 132 and snap hinge 136 arecentered at opposite sides of the cover 128, along the lateral X axis ofthe cover 128. Web sections 140 run generally parallel to a longitudinalY axis between column legs 144 and between grooves 130 on the under sideof the cover 128. The web sections 140 include a capture element 142 andelevated ends 145 extending from the web sections 140.

As shown in FIG. 19, the device 124 may also include a base 126. Thelocating elements 150 on the base 126 include a front pair 152 and aback pair 154 of locating elements arranged in a front to back directionas indicated by arrow 49. In general, the locating elements 150 may besubstantially symmetrical side-to-side about the longitudinal axis orcenterline Y. The locating elements 150 help restrain a catheter andcatheter fitting of various shapes and sizes and help preventsubstantial side-to-side, back-to-front, axial and rotational movementof such catheters and catheter fittings on the base 126. At the foot ofa locating element 150 is a ridge 155 and positioned in between thefront pair 152 and back pair 154 of locating elements is a bar 157running on either side of the arrow 49 and generally parallel to arrow49. A bottom latch 159 and snap hinge base 158 are centered at oppositesides of the base 126, along the lateral X axis of the base 126. Sidewalls 156 may extend up form the base along the perimeter of the base126.

In one embodiment the locating elements 150 are arranged such that afront locating element 152 is separated from a back locating element 154by a dimension EE which extends from the inner tip of 152 straight backand perpendicular to 154. Also, the inner edge of the first or rightback locating element 154 may be separated from the inner edge of thesecond or left back locating element 154 by a dimension GG runninggenerally parallel to a lateral axis X. Also, the inner edge of thefirst or right front locating element 152 may be separated from theinner edge of the second or left front locating element 152 by adimension HH running parallel to dimension GG. In one embodiment,dimension GG may be greater than dimension HH. In another embodimentdimension GG may be about 130 to 170% of dimension HH or more preferablyabout 140 to 160% of dimension HH.

As shown in FIG. 20, the device 124 operates such that the cover 128 isattached by the snap hinge 136 to the snap hinge base 158 of base 126and the cover 128 can rotate down onto the base 126 into a closedposition where the latch 132 and bottom latch 159 engage. In a closedposition the capture element 142 on the web sections 140 is adapted tocontact and compress the top of a catheter fitting held within device124. The capture elements 142 help compress and grip catheter fittingsof various shapes and sizes (e.g., by compressing the body and/or wingsof a catheter fitting) securely holding the catheter fitting in placeand preventing substantial movement of the catheter fitting such as inan axial, side-to-side, back-to-front, up and down and rotationaldirection. The capture elements may compress the catheter fittingagainst the ridge 155 and/or bar 157. The ends 145 of the web sections140 serve a similar function as the locating elements discussed above asthey also help restrain a catheter fitting and help prevent substantialside-to-side, back-to-front, axial and rotational movement of thecatheter fitting. The web sections 140 including capture elements 142and ends 145, as well as bars 157 and ridges 155, may be solid or springmolded and may be made of various materials as discussed above.Optionally, a base with no locating elements may be used with the cover128 for compressing and holding a catheter.

FIG. 21 shows securing device 170 having a base 176 and cover 178. Thedevice is attached to an adhesive pad 162. This embodiment operates muchlike the embodiments of FIGS. 16-20 described above for securingcatheters and catheter fittings having various shapes and sizes. Thebase 176 and cover 178 may snap fit together with or without a hingefeature.

FIGS. 22-29 show the universal catheter securement device 20 in use withvarious different types of catheters. With some catheters, as shown inFIGS. 22, 24, 27 and 29, the wings 200 of the catheter 32 are restrainedagainst virtually any longitudinal movement by the front and rearlocating elements. With other catheters, such as shown in FIGS. 23, 26and 28, the wings 200 of the catheter are narrower or smaller, leaving agap between the locating elements. This would nominally allow thecatheter to shift longitudinally under force (e.g., with pulling on thecatheter tubes). However, when the cover is closed, the catheter body202 and/or the wings are clamped tightly by the capture elements. Thislargely prevents any extensive inadvertent and undesirable movement ofthe catheter, even though there may be no direct physical contact with afront or rear locating element.

FIG. 30 shows an alternative embodiment of a base 180 for use in asecuring device. The locating elements 182 on the base 180 include atleast one front wall 183 and a pair of back walls 184 arranged in afront to back direction as indicated by arrow 49. In general, thelocating elements 182 may be substantially symmetrical side-to-sideabout the longitudinal axis or centerline Y and they are arranged toposition and hold catheter and catheter fittings of various shapes andsizes to prevent substantial movement of such catheters and catheterfittings in various dimensions. The front wall 183 may be angled and asemicircular trough 185 may be positioned slightly forward of the frontwall 183 and may be connected to the front wall. The back wall 184 isconnected to a post 186. A bottom latch 187 and snap hinge base 188 arecentered at opposite sides of the base 180, along the lateral X axis ofthe base 180. The base 180 may snap fit to a cover with or without ahinge feature. Side walls 189 may extend up form the base along theperimeter of the base 180 and spikes 190 may extend up from the base andrun in a line on either side of arrow 49, between a front wall 183 andback wall 184. The base 180 can operate in conjunction with a cover in amanner to compress and/or restrain catheters and/or catheter fittings ofvarious shapes and sizes and prevent their substantial movement invarious dimensions.

In one embodiment the locating elements 182 are arranged such that afront wall 183 is separated from a back wall 184 by a dimension JJ whichextends from a mid-point on an inner surface of the front wall 183,straight back and generally parallel to the longitudinal axis Y, to thepost 186. A front wall 183 may also be separated from a back wall 184 bya dimension KK which extends from the outer edge of the front wall 183to the outer edge of the back wall 184. Also, a first or right post 186may be separated from a second or left post 186 by a dimension LLrunning generally parallel to a lateral axis X. Further, a semicirculartrough 185 may have a dimension MM running generally parallel todimension LL. In one embodiment, dimension JJ is greater than dimensionKK. In one embodiment, dimension LL is greater than dimension MM. Inanother embodiment dimension JJ may measure about 0.33 to 0.37 inches,preferably 0.34 to 0.36 inches, or more preferably 0.35 inches in lengthand dimension KK may measure about 0.31 to 0.35 inches, preferably 0.32to 0.34 inches, or more preferably 0.33 inches in length. Also,dimension LL may measure about 0.41 to 0.45 inches, preferably 0.42 to0.44 inches, or more preferably 0.43 inches in length and dimension MMmay be about 0.15 to 0.19 inches, preferably 0.16 to 0.18 inches, ormore preferably 0.17 inches in length.

In an alternative design, the device may use a generally plane cover andbase, with the device not having locating elements 40 and/or spikes 48.In this design, the cover and base act as simple clamping elements tosecure the catheter. With sufficient clamping force applied, the coverand base can restrain the catheter against significant movement, withoutusing locating elements, such as walls, posts, etc. Force multiplyingelements, such as levers, cams, screw threads, etc. may be used in thistype of design to provide adequate clamping force.

The above securing devices may be molded plastic or made of othermaterials suitable for use with patients. Any of the bases or coversdescribed may be provided in the shapes shown or in other shapes aswell, including irregular shapes. Outer walls extending up from a basearound the outside of the locating elements may also be provided to helpalign and engage a cover onto a base. Also, the various embodiments ofsecuring devices described above may be attached to a patient in avariety of ways, e.g., with a pad as shown in FIG. 2, or with otheradhesive means.

In other embodiments, a securing device for holding catheters and thelike in place advantageously has two parts. A base attached to a padforms one part. A cover is the other part. The cover may optionally betethered to the base. The pad preferably has an adhesive back surfacefor attaching the pad to the patient's skin. The base on the pad haspositioning elements such as walls or surfaces adapted to fit securelyaround a catheter fitting. The catheter fitting may be placed into oronto the base from above. The positioning elements prevent anysubstantial movement of the catheter fitting, in two dimensions,relative to the base or pad, e.g. in the front/back and left/right sidedirections. The cover is attached to the base over the catheter fitting.One or both of the base and cover have latching elements for holding thecover onto the base. The cover prevents movement of the catheter fittingin a third dimension, i.e., vertically up and out of the base.Consequently, after the cover is attached to the base over the catheterfitting, the catheter fitting and the catheter are securely held inplace on the patient. The catheter may be released and removed from thebase by temporarily disengaging the latching elements. The latchingelements may be disengaged by, for example, squeezing the sides of thecover. The catheter can therefore be quickly and easily attached to orremoved from the patient. Such devices may be used with, e.g., PICClines, IV catheters, Foley catheters, heart catheters, J-loops, andvarious other catheters, as well as tubes, cables, lines, and othermedical devices.

For example, FIG. 31 shows an embodiment of a securing device 320 havinga base 326 attached to a pad 322. The pad 322 is flexible to conform tothe patient's arm or other site. The back side of the pad 322 preferablyhas one or more peelable strips over an adhesive layer or surface. Thespecific pad shape and size is not essential and various alternativesmay be used. In the example shown in FIG. 31, the pad 322 generally isoval or round, and with a major diameter of from about 1-6, 2-5 or 3-4inches. The pad does not need any suture holes.

As shown in FIGS. 31-34, a base is attached onto the top side of the pad322 at a generally central location. The base 326 has positioning walls350 shaped and dimensioned to fit securely around a fitting 332 on acatheter 330. For the catheter 330 shown in FIGS. 32 and 33, fourseparate positioning walls 350 are used. In this case, the catheterwalls 350 are adapted to fit around the curved ends of the fittingplate. The walls 350 are spaced apart in the back to front direction(indicated by the arrow 356 in FIG. 32) by a dimension just nominallygreater than the width of the fitting plate 334. Similarly, the walls350 are spaced apart side to side by a dimension nominally greater thanthe length of the fitting plate.

Referring to FIGS. 32-34, outer walls 352 extend up from the base 326around the outside of the positioning walls 350. The outer walls arelower than the positioning walls. Latching arms 340 extend up generallyfrom opposite sides of the base 326. An angled face or surface 344 isprovided at the top or head 342 of each of the arms 340. The base 326may have a tapered or inclined edge or rim 354. One or more throughholes 346 may be provided in the base 326, if desired, for manufacturingpurposes. An arrow symbol 356 may be provided on the base 326 and/or thecover 328, to indicate how the catheter 330 should be installed into thedevice 320.

As shown in FIGS. 32 and 35, the cover 328 has latching arms 366, withan angled surface or face 370 at the outer or lower end 368 of each arm366, similar to the latching arms 340 on the base 326. In the oblongcover 328 shown in FIG. 35, the arms 366 are centered at opposite sidesof the cover, along the major axis of the cover. Web sections 362 runbetween column legs 360 on the bottom or under side of the cover 328.The column legs extend out beyond the latching arms 366. A contact orland surface or area 364 on the web sections 362 are adapted to lightlycontact the top of the catheter fitting 332 when the cover 328 isattached to the base 326.

In use, after the catheter has been placed, the skin at the securementsite is preferably cleaned. The catheter fitting 332 is then placed intoor onto the base 326, as shown in FIG. 33. Land or boss areas 351 may beprovided on the floor of the base 326, within the positioning walls 350,as shown in FIGS. 33 and 33. These areas 351 may be used, if desired, tosupport the catheter fitting 332 off of the floor of the base 326. Thecover 328 is then attached to the base 326 over the fitting 332, asshown in FIG. 31. The outer walls 352 may align with and engage againstinner rim surfaces 365 on the cover 328, as shown in FIG. 35. Thisinteraction, if used, helps to align the cover onto the base, and tosecurely attach the cover to the base. The column legs rest on flatouter areas of the base.

The column legs 360 are dimensioned so that when they bottom out on thebase 326, the contact surfaces 364 rest on the catheter fitting 332. Thelegs 360 prevent crushing or deformation of the catheter fitting, bykeeping the contact surfaces 364 at a specified dimension above the basefloor. As a result, the catheter fitting cannot be crushed, even if thecover is forcefully clamped down onto the base. The fitting 332 issecurely held in place (horizontally) on the base between thepositioning walls and is held in place vertically between the floor ofthe base 326 and the contact surfaces 364 of the cover.

As the cover is moved down onto the base 326, the angled surfaces 344 onthe base latching arms 340 engage the angled surfaces 370 on the coverlatching arms 366. This provides for a cover self aligning operation.The arms 340 and 366 are somewhat resilient and can flex slightly underload in the lateral direction. As a result, as the cover is moved intoengagement with the base, the base latching arms 340 flex slightlyoutwardly, and the cover latching arms flex slightly inwardly. Thesurfaces 344 and 370 of the arms 340 and 366 slide against and then passby each other. The arms 340 and 366 then flex back to near theiroriginal lateral positions, locking the cover 328 onto the base 326. Thepeel strip(s) are removed from the back of the pad 322, and the pad isplaced onto the prepared securement site. The device 320 then preventsvirtually any movement of the catheter fitting 332, which is joined toor part of the catheter 330. A cut out 324 may be provided at the frontof the pad 322 to allow the base 326 to be closer to the incision orcatheter entry point.

The catheter 330 may be removed by squeezing the sides of the cover 328towards each other. The cover 328 is slightly flexible. Squeezing causesthe cover to curve or bow up. As the cover curves, the arms 366 aredrawn inwardly enough to pull the ends 368 of the arms 366 on the cover328 away from the ends 342 of the arms 340 on the base 326. The head orends 342 and 368 can then pass by each other as the cover is lifted offof the base.

FIGS. 36-38 show another embodiment of a securing device 380 for usewith a catheter 390 and catheter fitting 392. The cover 388 has curvedcontact surfaces 364 matching the top of the fitting 392. The base 386has positioning walls 350 adapted to fit around the fitting 392.

FIGS. 39-42 show another embodiment of a securing device 400 for usewith another type of catheter 410 and catheter fitting 412. As shown inFIG. 40, the positioning walls 350 on the base 406 are segmented. Thecover 408, as shown in FIG. 42, includes an opening 416 in a rear wall414.

FIGS. 43-45 show another embodiment of a securing device 415 for usewith yet another type of catheter 440 and catheter fitting 417. In thisdesign, four positioning walls 350 are provided on the base 436. Grooves418 may be provided on the cover 408 to make the cover more flexible. Asshown in FIGS. 41, 43 and 46, ramps or ridges 413 may be provided on thebase floor near or adjoining one or more of the positioning walls 350.These features may be used to set the orientation of the catheterfitting in the device. FIGS. 46 and 47 show a base 419 similar to thebase 436 shown in FIG. 43. The base 419 is generally oval shaped asopposed to the more rectangular base 436 shown in FIG. 43.

The devices shown in FIGS. 36-47 operate in the same way as the device320 shown in FIGS. 31-35 and described above. The base and cover in eachdesign may be molded plastic. The positioning walls 350 may besegmented, as shown in the drawings, or continuous. Indeed, a singlecontinuous positioning wall surrounding the catheter fitting 417 on allsides may be used. Alternatively, multiple short spaced apart wallsegments around two, three or more sides of the fitting may also beused. The wall segments may be various shapes, including generallyrectangular, as shown in FIGS. 45-47, as well as round, square,hexagonal, etc. Positioning or locating elements, such as the walls 350,may optionally also be provided on the cover. Moveable or adjustablepositioning elements or wall segments may also alternatively be providedon the base. If used, these may have a single direction or ratchetfeature, so that they can move only inwardly to contact the sides of thecatheter fitting. Moveable positioning elements may allow use of asingle device with more than one specific type of catheter.
